A cylindrical tank, 0.42 m in diameter, drains through a hole in its bottom. At the instant when the water depth is 0.73 m, the flow rate from the tank is observed to be 5 kg/s. Determine the rate of change of water level at this instant.
Answers: 3
(1)
- Current mass of water inside the tank, measured in kilograms.
- Diameter of the cylindrical tank, measured in meters.
- Depth of the water in the tank, measured in meters.
), measured in kilograms per second, by considering geometric characteristics of the cylinder (
) and the fact that water is an incompressible fluid (
):
(2)
is the rate of change of water level, measured in meters per second. 
, 
and 
, then the rate of change of water level is:
![\frac{dh}{dt} = \left[\frac{4}{\pi\cdot \left(1000\,\frac{kg}{m^{3}} \right)\cdot (0.42\,m)^{2}} \right]\cdot (-5\,\frac{kg}{s} )](/tpl/images/0891/7312/4db3a.png)

Refrigerant-134a enters the compressor of a refrigerator as superheated vapor at 0.14 mpa and -10°c at a rate of 0.05 ka/s and leaves at 0.8 mpa and 50°c. the refrigerant is cooied in the condenser to 0.72 mpa and 26'c. it is then throttled to 0.15 mpa. sketch the t-s diagram for the system and evaluate: 6) the rate of heat removai from the refrigerated space (kw), it) the power input to the compressor (kw), ii) the isentropic efficiency of the compressor (%), and iv) the cop of the refrigerator.
